FRESH AIR INTAKE
To ensure trouble-free operation the stove/fireplace
must have the necessary air available for combustion
and this is provided through the fresh air intake.
The fresh air intake must:
 have a total free cross section at least equal to the
size given in the paragraph “TECHNICAL DATA”;

be protected by a grille or suitable guard provided
it does not reduce the minimum recommended
section;

be in a position whereby it cannot be obstructed.
The airflow necessary for the fire may be obtained in
different ways:

through a fresh air intake direct into the room of
installation;
 with ducting through pipes direct to the room of
installation, increasing the recommended minimum
free cross section by at least 15%;

from an adjacent room to the place of installation
provided this air flows freely through permanent
apertures communicating with the outside.
The adjacent room from which air is taken
must not have a low pressure compared to
the exterior due to a counter draught
caused by the presence in that room of another
appliance in use or of a suction device.
The permanent apertures in the adjacent room must
comply with the requirements given above.
Combustion air must not be taken from adjacent
rooms used as a garage or a combustible materials
store or for activities posing a fire hazard.
